The 8-spring hub features RAM poly-coil damper springs encased in polyurethane; units can handle three times the shock load of just the coil spring (standard in all RAM Competition Discs). Competition pressure plates provide 30% more clamping force than stock and meet SFI specifications. Even at this high level of performance, RAM Powergrip Clutches offer good driving characteristics with comfortable driver control. Kits include disc, pressure plate, alignment tool, and release bearing unless otherwise noted.
